Most supply chains suffer shortages and excess stock at the same time. The cause is the same: replenishment driven by forecast instead of actual consumption.
We rebuild the chain around pull — so the right product is available at every level, with the least inventory needed to guarantee it.
The core shift: stop ordering on prediction and batch-size formulas, start replenishing what the chain actually consumed — every day, at every link.
Shops and end points report real daily demand upstream. Regional distribution ships based on what was sold — not on what a forecast said would sell.
Central distribution receives daily consumption reports and ships accordingly. Suppliers receive frequent, smaller orders — starting with twice the previous frequency.
Inventory target = demand during reliable replenishment time, plus protection for variability. No need to over-engineer it — the system self-corrects from here.
Buffer status — green, amber, red — becomes the single priority signal across the chain. Targets adjust dynamically as demand and reliability change.
As replenishment gets faster and more reliable, targets drop automatically. Availability goes up while cash tied in stock goes down.
The strategic position where forecast-driven production meets consumption-driven replenishment. Placed correctly, it cuts customer lead time while minimising total inventory.
Most chains are under-protected (shortages) or over-protected (excess stock). Buffer management navigates between the two by making buffer status visible and actionable.
Daily replenishment runs on actual consumption. Forecast is reserved for decisions you can't reverse quickly: capacity, long-lead-time material, new distribution points.
Demand-driven algorithms with dynamic adjustments, pipeline control, and continuous monitoring — supporting the right make / buy / ship / priority decision at every level.
Smaller lots mean shorter lead times and less inventory. The real obstacle is usually changeover time — improve that, and lot size follows.
In retail, shelf space is the constraint. Measure the throughput each product generates per unit of shelf, and exchange slow movers for better ones — don't discount them.
A synchronized chain doesn't stop at your own walls. The biggest inventory reductions come from bringing suppliers into the system.
Suppliers earn bonuses tied to delivery reliability and your inventory turns — so their incentives point at your availability, not just their invoice.
Suppliers see which orders currently endanger performance. Their lead time and reliability improve — and your inventory targets drop with them.
When a supplier's buffer sits permanently in the red, the fix isn't a bigger buffer — it's helping the supplier elevate their own constraint. One of the highest-leverage moves in any chain.
Economic Order Quantity optimises per item but ignores the system's constraint — typically producing large batches, high inventory, and long lead times.
Uncertainty isn't reduced by predicting better — it's reduced by needing to predict less. Shortening decision and replenishment time beats any forecasting model.
Lower labour cost doesn't automatically mean more profit. A distant factory running efficiently at scale is rarely synchronised with demand — producing shortages and excess at once.
Constraints & Demand Synchronization — our decision-support system that turns these principles into daily practice across your entire chain.
Demand-driven inventory management for finished goods, semi-finished and raw materials — C&DS Classic algorithms or DDMRP logic, with dynamic adjustments and pipeline control.
Make-to-order, make-to-stock and hybrid models. Every customer request is checked against real capacity and inventory before you commit to a date.
Execution priorities everyone understands, online delivery-performance visibility, and Pareto analysis of flow obstacles to drive on-going improvement.
Synchronized supply chains we have implemented — with C&DS running them every day.
Dynamic Replenishment and Buffer Management across 5 plants and 3 distribution centres. Result: very high service levels with a –40% inventory reduction through the global supply chain — and a planned new UK warehouse cancelled, the existing one running at half capacity.
